Show HN: Programmatic – a REPL for creating labeled data Hey HN, I’m Jordan cofounder of Humanloop (YC S20) and I’m excited to show you Programmatic — an annotation tool for building large labeled datasets for NLP without manual annotation . Programmatic is like a REPL for data annotation. You: 1. Write simple rules/functions that can approximately label the data 2. Get near-instant feedback across your entire corpus 3. Iterate and improve your rules Finally, it uses a Bayesian label model [1] to convert these noisy annotations into a single, large, clean dataset, which you can then use for training machine learning models. You can programmatically label millions of datapoints in the time taken to hand-label hundreds. What we do differently from weak supervision packages like Snorkel/skweak[1] is to focus on UI to give near-instantaneous feedback. We love these packages but when we tried to iterate on labeling functions we had to write a ton of boilerplate code and wrestle with pandas to understand what was going on. Building a dataset programmatically requires you to grok the impact of labeling rules on a whole corpus of text. We’ve been told that the exploration tools and feedback makes the process feel game-like and even fun (!!). We built it because we see that getting labeled data remains a blocker for businesses using NLP today. We have a platform for active learning (see our Launch HN [2]) but we wanted to give software engineers and data scientists a way to build the datasets needed themselves and to make best use of subject-matter-experts’ time. The package is free and you can install it now as a pip package [2]. It supports NER / span extraction tasks at the moment and document classification will be added soon. To help improve it, we'd love to hear your feedback or any success/failures you’ve had with weak supervision in the past. [1]: We use a HMM model for NER tasks, and Naive-Bayes for classification using the two approaches given in the papers below: Pierre Lison, Jeremy Barnes, and Aliaksandr Hubin.
